An integrated sliding bead allows the tension to be adjusted for a more secure fit when conditions call for it, helping keep eyewear in place while remaining easy to loosen when desired. Measuring 19 inches from end to end, the Bowline combines simple adjustability with durable construction for dependable eyewear retention on and off the water.
